43A Motor Driver Module for Robots Smart Car Current Limit Control

43A Motor Driver Module for Robots Smart Car Current Limit Control Description

Key benefits Simple wiring: only four connections to your MCU-GND, 5V, PWM1, PWM2-so you can get bidirectional motor control up and running quickly. MCU protection: the module uses an isolation chip with a 5V supply to isolate and protect the MCU. The isolation power can share the MCU 5V supply if desired. Reliable control and feedback: two PWM inputs support bidirectional motor control at up to 25 kHz, and the module provides errorsignal outputs related to heat flow monitoring for fault indication. Serviceability and cooling: the PCB includes a motoroutput voltage indication and pads where a heatsink can be soldered for improved thermal performance. Visual status: onboard 5V power indicator makes powerup checks fast and reliable. What it does (function) Provides bidirectional drive for DC motors using two PWM inputs (PWM1 and PWM2). Monitors thermal/heatflow conditions and provides error signal output(s) when thresholds are exceeded. Indicates power presence and motordriver output voltage for troubleshooting. Offers physical provision to attach a heatsink for better heat dissipation. Compatibility and connections Interfaces to any MCU that provides PWM outputs at rates up to 25 kHz. Wiring required from MCU: GND, +5V, PWM1, PWM2. Isolation chip requires a 5V supply; it can share the MCU 5V rail if system design allows. PCBmounted design with standard electronic components; heatsink can be soldered directly to the board. Performance and electrical notes PWM input frequency: up to 25 kHz for smooth motor control. Errorsignal outputs indicate thermal/heatflow related faults for both channels. Onboard LED indicates 5V power presence; motoroutput voltage test points/indication available on the driver output end. Designed to protect the MCU via 5V isolation circuitry. Physical and material attributes Compact PCBmounted module constructed from standard FR4 and electronic components suitable for soldering heatsinks and wiring. Provides pads and mounting points to attach additional cooling hardware. Typical applications Mobile robotics: bidirectional control of drive motors where MCU isolation and compact mounting are required. RC vehicles and small electric platforms: frequency PWM control for smoother speed regulation and quick direction changes. Small automation and conveyor systems: reliable motor driving with thermal/error signaling and the option to add a heatsink for continuous operation. Installation tips Connect GND and +5V first, confirm the onboard 5V LED lights, then connect PWM1 and PWM2 from the MCU. If your design requires strict isolation, supply the isolation chip with a dedicated 5V source; otherwise sharing the MCU 5V is supported. If continuous load operation is expected, solder a heatsink to the provided pads to reduce thermal stress and rely on the errorsignal outputs for fault detection. What to expect A compact, easytowire motor driver module that supports bidirectional PWM up to 25 kHz, offers thermalrelated fault signaling, provides basic voltage indication at the motor output, and includes design provisions for heatsink attachment and MCU protection via 5V isolation.
